Sebastiano Vigna

Sebastiano Vigna is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sebastiano Vigna rather than just read about it. In short: Sebastiano Vigna (born 1967) is a professor of computer science at the University of Milan. He created the xorshift+ and xoroshiro128+ pseudorandom number generators.

Key takeaways

Sebastiano Vigna belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Sebastiano Vigna to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Sebastiano Vigna from memory before moving on to harder problems.

Reference excerpt

Sebastiano Vigna (born 1967) is a professor of computer science at the University of Milan. He created the xorshift+ and xoroshiro128+ pseudorandom number generators. Xorshift128+ is used in the JavaScript engines of Chrome, Firefox, and Safari. In 1991, he received a laurea in Mathematics and in 1996 a Ph.D. in computer science; both from the University of Milan. He developed UbiCrawler, a web crawler, in a collaboration with others. He worked extensively on graph algorithms such as HyperBall. He used this algorithm, together with researchers from Facebook and others, to compute the degrees of separation on the global Facebook network, which resulted in an average distance of 4.74.

Worked examples

Example 1 — a first encounter with Sebastiano Vigna

Start with the simplest possible case. Write down what Sebastiano Vigna claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sebastiano Vigna before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sebastiano Vigna ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sebastiano Vigna

In research: Sebastiano Vigna appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Sebastiano Vigna in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Sebastiano Vigna is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1967 births, Academic staff of the University of Milan, Computer scientist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Sebastiano Vigna outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
